Ghost hunter Verity Long is overdue for a little R&R (rest and romance) with her boyfriend, Ellis, and a vintage train trip through the Tennessee mountains seems like just the ticket. The Sugarland Express carries history and nostalgia in every compartment, and Verity is determined to enjoy it-without ghostly interference. But the ghosts have other plans... On a dark, desolate night nearly a century ago, the train was stranded in the mountains, and a young woman was found stabbed to death in her locked compartment. The murder was never solved, and a ghostly Belgian detective is still pursuing the case from the grave. To Verity's dismay, all of the ghostly suspects are back. And when history repeats itself and a new murder mirrors the old, it's up to Verity and her friends to discover which of the passengers-dead or alive-could be behind the murders before the killer strikes again.
